Oliver said most local waterways are running "bankful" as of 8 p.m. Wednesday, but flooding from Willow Creek and nearby Soldier and Boyer rivers are especially concerning. A flood watch remains in the area until 7 p.m. Thursday, according to the National Weather Service. A flood warning is expected to take effect over the weekend.

"(Soldier and Boyer rivers) have breach points or are overtopping levees and there were some areas affected there, although no populations were evacuated. It's just precaution taken," he said. No injuries have been reported in Missouri Valley but several roads have been closed in the area.

A portion of Highway 30 has been shut down from I-29 to Denison and traffic is being rerouted, Oliver said, per the Iowa Department of Transportation.

Some county roads are under water and motorists are encouraged to check the DOT's 511 app or head to 511ia.org for the latest traffic updates.

"Pay attention to the road-closed signs and don't drive through the water," Oliver said. "Just be careful. If you don't have to be out, then don't be out."

Just south of Missouri Valley, Interstate 680 been closed, according to the Iowa DOT, because of rain and melting snow. Sgt. Nathan Ludwig, with the Iowa State Patrol, said the roadway isn't yet underwater, but that could happen soon.

"Several roads in the area are also being impacted by flood waters creating additional closures. Travelers are urged to check 511ia.org for current flood-related closures and detour routes," reads a release from the DOT.
